To all whom it may concern:

Be it known that I, HOWARD D. GOLMAN, a citizen of the United States, residing at Rockford, in the county of 'Winnebago and State of Illinois, have invented certainnew and useful Improvements in Mechanical Movements, of which the following is a specification.

The invention herein shown relates to a means for feeding two members at different rates of speed by means acting directly upon one of said members,

In the drawings I'have illustrated the invention in connection with a machine for drawing warp threads through the heddle eyes of loom harnesses and between the.

dents of a loom reed. Said machine comprises a carnage m which the harnesses are suspended and upon which the reed is loosely or slidably carried, said carriage bemg fed with relation to the drawing-1n mechanisms by a device which positi ely feeds the reed. Owing to the difference in length of the harnesses and the reed, they would get out of proper relation if fed at the same rate through the machine.

The present. invention, therefore, providcs means for causing the harnesses to more more rapidly or more slowly than the reed, as may be desired.

In the' accompanying drawings, Figure l is a perspective View of a portion of a warp-drawing machine embodying the features of my invention. Fig. 2 is a side elevation of sour. of the parts comprised in line present invention. Fig. 3 is a fragmental view of the carriage, illustrating the means for slidably supporting the reed. Fig. 4 is a detail view of the reed-feeding device.

Referring to the drawings, 1 indicates the carriage for the loom harnesses a a and the loom reed b. Said carriage is provided with means for movably support ing it, comprising, in this-instance, bearing rollers 52, only one of which is seen in the drawings, said bearing rollers running upon a track 3 fixed in the framework of the machine. For convenience, I will herein designate the end of the machine from which the carriage 1 starts the head end of the machine, and the opposite end the foot end of the machine.-

\ members 4 in which are formed two grooves 5 to the upper end of a screw 12. Said screw gated guide slot 25 in said rod.

The carriage 1 comprises two frame 5 to receive the longitudinal side bars of the reed. Said reed is loosely held in the carriage 1 by means of catches 6 fixed upon a rock shaft 7 said rock shaft being operated by means'of cranks 8.

Supported in any suitable way at the side of the track 3 is a rail 9 inclined at an angle with the track 3. In the present instance, I have shown the end of the rail 9 toward the starting position of the harness and reed carriage as being pivotally mounted at 10 upon the track 3, the opposite end of said railbeing adjustably supported in a saddle ll pivotally connected extends through an opening 13 in a block ]4- rigidly mounted in the machine frame. Nuts 15 on said screw at opposite sides of the block 14:; provide means for reciprocating the screw and for looking it in position. To one of the frame members of the can riage 1 is pivoted a bell-crank 16'. One arm 17 of this bell-crank is pivotally con-- nected with a rod 18 carrying at its lower end a roller 19 adapted to run upon the rail 9. The rod 18 is extensible in length, being made of two telescoping sections 18* and 18 arranged to be fixed in adjusted position by means-of a set screw 20. A guide 21 fixed to the carriage 1 slidably embraces the rod 18. The other arm 22 of the bell-crank 16 is pivotally connected with a rod 23, against the opposite end of which the reed b is arranged to bear either directly or indirectly. In the present instance I have shown a spring-cushioning device 34 between said rod and said reed. The rod 23is preferably guided by means of a screw 24'extending through an elon- In the machine illustrated in the present drawings the reed b is moved by means of a feedin finger 26 adapted to enter be tween ad acent dents of the reed and ush said reed through the machine. The eeding finger 26 is fixed to the upper end of an arm 27, said arm being fixed tori shaft 28 slidably and rotatably mounted in bearings 29 in the machine frame. .To th shaft 7 28 is fixed an arm 30 adapted to engage the periphery of a. cam 31 mounted on a shaft 32 rotatably supported in the reed b, then moved toward the foot or the machine, then rocked away from the reed, and finally moved toward the head of the machine. The feeding linger 26 conseqnentiy is first inserted between two dents of the reed, then moved sidewis'e to force the re d toward the foot of the machine, then withdrawn 312' said reed, and finally returned to its initial position; The reed l) thus positively moved toward the front end of the mechine by the feeding finger 26, the reed hearing against the end of the rod :4 Assuming the mil 9 to be in the position shown in Fig 2, it will be seen that any movement communicated to the rod 23 by the reed 6 will be transmitted to the car' risge 1 though the hell-crank 1 5. The free end of the arm 17 of said helhorsnlr being maintained at a constant height above the inclined rail 9,, the force exerted upon the arm of said. bellcrank by the feeding linger 26 results in an oscillation as Well as s bodily forward movement of said helloranlr. The forward movement of the pivotol center of said bell-crank produces a forward movement of the harness and reed arrisge l, and the oscillation of said bellcnnl: causes a difference in the rates of movement of the reed and the carriage.

The. forward movement of the pivotal cellter of the bell-crank i6, icwill be observed, is greater than the forward movement of the free end or" the'arm of said bell-cranlr when the rail 9 is inclined iipivardly toward the foot of the machine, resulting in a relative movement between the harness and reed carriage 1 and the reed b, said reed slipping in the grooves The mil 9 is adjusted to such an angle that the diilerence in the rates '5' travel of the harnesses and the reed will hesufi'icient to compensate for the unequal 5 read of said reed and said harnesses. When the rail 9 is inclined downwardly tovvord the foot of the machine, the harnesses will move more slowly than the reed.

It will be understood that any suitable means may be employed for moving the reed, and that said reed may be supported upon the harness and reed carriage in other positions and through the agencies of other devices than those herein shown.

It will also be apparent that the difierential feed mechanism of this invention racy which rail supports a portion of the pivoted member, whereby movement imported to nieinber carried by the carriage cause; differential movement of said last tioned member and said carriage.

2. The combination of a harness and carriage in which creed may be loosely for rectilinear movement, a lever pivoted on said carriage, against one arm of which lever the reed is arranged to press, means slidably engaging the other arm 01 said lever to rcsist 'the pressure of the reed, said lever-engaging means extending at an angle to the co, rings-supporting means, and need engagicog means to move the reed cgeins' the lever, whereby differential movement i imported to the reed and the hernesscsrrisge.
